Every time someone says shit like "locked into the Apple ecosystem", god kills a kitten. Lots of people switch back and forth between iOS and Android.
Nobody's going to go for USB-C on their iPhones if they can get Lightning ports. The Lightning port is far superior mechanically (both more durable and easier to clean from debris) and unlike most Android phones, not attached to the mainboard - so it can be replaced if damaged.
Lightning ports may well be technically superior (I can't really judge as I've had dozens of devices using USB-C, 95% of the time with no issues, but relatively few occasions to use lightning ports - thought I do have an iPad that's bricked currently because I can't find a cable for it), but if Apple is unwilling to license the technology to other manufacturers then there's no chance of it ever being any sort of universal standard.
Personally I'd rather hoped that by now we didn't need cables/plugs at all!
